Georg David Dietz from Erbach and his wife Angelika immigrated first to the colony of Julianenebene in Denmark. David and his son (also Georg David) arrived 15 June 1765 in Shcherbakovka and are listed there on the 1767 census living in Households No. 5 (father) and No. 6 (son). Sometime before 1796, the entire Dietz family moved to Kratzke.
